Abstract
Aiming at providing a brake hub with simple structure and reliable performance, the utility model discloses a brake hub, belonging to automobile components. The utility model comprises at least three tile-like gland bushes(3) which are symmetrically fixed at intervals on the inner wall of a hub body. Simple in structure, safe and reliably, the utility model is an ideal brake hub for large motor vehicles.
Description
Technical field: the utility model relates to a kind of auto parts machinery, relates in particular to a kind of brake hub.
Background technique: well-known, the full-sized car sole mass is big, inertia is also bigger, generally all will brake jogging when lower long slope; Because the violent for a long time friction of brake hub and brake block, brake hub is generated heat easily and is produced high temperature, so full-sized car need carry out spray cooling to brake hub when lower long slope.Yet the brake hub of full-sized car generally all is that brake failure is broken, caused to brake hub easily by abrupt temperature drop under the condition of high temperature, usually cause great traffic accident by castiron monolithic construction at present.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of brake hub of simple in structure, reliable performance.
To achieve these goals, the utility model by the following technical solutions: it comprises the hub body; At least the fixing inwall that also is distributed in the hub body symmetrically of the liner of griffith woodsorrel herb sheet keeps at a certain distance away between each liner.
The hub body is made by cast steel, and liner is made by cast iron.
Compared with the prior art, the utility model since on the basis of traditional brake hub with original cast iron hub structural reform for cast steel hub body, and liner is set symmetrically at the inwall of this hub body; Therefore, when the hub body is at high temperature cooled off suddenly, can not break, thereby reach the purpose of safety traffic.In addition, after liner is worn, can pass through the mode place under repair of replacing, and needn't whole brake hub be changed, thereby save maintenance cost greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Among the figure: hub body 1 rivet 2 liners 3
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～2, the hub body of cylinder type 1 is made by cast steel, and the liner of tile 3 is made by cast iron; Three or more liner 3 is kept at a certain distance away between each liner 3 on the inwall of hub body 1 by rivet clasp symmetrically by rivet 2.
In brake process, owing to liner 3 and brake block friction produce heat, hub body 1 expanded by heating, the gap between the liner 3 enlarges thereupon; And when brake hub was lowered the temperature, hub body 1 shrank, and the gap between the liner 3 reduces thereupon, so hub body 1 can not break.
Claims (2)
1. a brake hub comprises the hub body; It is characterized in that: the inwall of hub body (1) is fixed and be distributed in symmetrically to the liner of griffith woodsorrel herb sheet (3) at least, and each liner keeps at a certain distance away between (3).
2. brake hub according to claim 1 is characterized in that: hub body (1) is made by cast steel, and liner (3) is made by cast iron.
